HEAD FOR FA BRIC TAKE-UP DEVICES FOR KNlTTlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 317,773, dated May 12,1885.

Application filed March 18, 1884. (N0 model.)

To all whom it may concern:

Be it known that I, HORACE L. HAYDEN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Heads for Fabric Take- Up Devices for Knitting-Machines;and I do hereby declare that the following is a full, clear, and exactdescription of the same;

My invention is an improvement in the swiveled head ordinarily used withthat class of circular-knitting machines in which the fabric is drawnupward as the work of knitting progresses.

It consists in the special construction of the swiveling devices, theobject being to lessen the friction, to prevent wabbling, and to preventalso the dripping of the lubricating oil upon the fabric.

In the accompanying drawings, Figure 1 representsin perspective myimproved s Wivelhead. Fig. 2 is a longitudinal vertical section of thesame. Fig. 3 is a detail view showing the swivel-rod with its cup insection.

The head A, with the hooks a a, is of ordinary construction.

The eye I; of the swiveling rod B is designed to be attached to a cordwhich passes over a pulley and is connected to a Weight. In the formheretofore used this rod passes through a hole in the center of the headA, and is no set underneath with a suitable interposed washer. Thisconstruction causes considerable friction. The parts Wear out rapidly,the head soon wabbles, and the oil used to lubricate the swivel drops onthe fabric.

In my improved construction I provide the under side of the head with ahollow nipple, d, the bore of which is continuous with the hole in thehead, and the end of which is beveled annular-1y, as shown at 1.

On the end of the rod B which is fitted to pass through the nipple is acup, D, of such an interior diameter as to receive the nipple and permitit to turn freely therein. The bottom of the annular space between theinterior surface of the wall and the rod B is inclined to correspondwith the end of the nipple, so that it remains centered after wear. Thenipple and cup are both hardened. A groove or annular chamber is formedon the inside of the cup, as indicated at e, and thus the capacity ofthe cup is increased. The cup is filled with oil, which, by therevolution of the head, is properly distributed. The bearing formed bythe nipple is long enough to maintain the head in position even afterlong use and wear.

I claim- 1. In combination with a suitable head, A, having devices forholding the fabric, a swiveling rod passing through the head andprovided with means for connecting it to a cord, and with a cup at itslower end, all substantially as described.

2. In combination with the head A, the nipple, the rod B, and the cup,all substantielly as described.

3. In combination with the head A, the

nipple having an annularly-beveled end, and

the cup with corresponding annular bottom,

all substantially as described.

4. In combination, the head A, the nipple, the rod B, and the cup havinggroove or annular chamber on its inner face, all substantially asdescribed.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.

HORAOE L. HAYDEN.
